The content of the invention
Invention problem to be solved
In LCD panel module, reflecting plate and panel sheet metal are installed with free state.In other words, only reflect
Complete cycle between plate and panel sheet metal is clamped, and more the central part toward reflecting plate more becomes free state.Therefore, because backlight
The impact of the heat in source etc., causes reflecting plate that the deflection of the reflecting plate of flexure or script flexure, flexure mode occur and changes.Root
According to the investigation of present inventor, learn that the main cause of the flexure is the increase and decrease of light quantity acquired by optical sensor.Think with
The large screen of liquid crystal image display device, the progress of slimming, deflection when reflecting plate bends also are becoming big.
But, patent documentation 1~4 record structure for the heat because of backlight etc. impact and reflecting plate occur flexure or
Deflection of person when reflecting plate occurs flexure because of the impact of the heat of backlight etc., that flexure mode changes this phenomenon is not any
Refer to.Additionally, for the flexure of reflecting plate is to cause the main cause of the increase and decrease of light quantity acquired by optical sensor also no instructive
Record.
According to the investigation of present inventor, it was found that following machine, i.e. even if making A-stage become tubular bolster
State very close to each other (or gap little state) also occurs following movement between reflecting plate：Because of the shadow of the heat such as backlight
Ring and said reflection plate occurs flexure, so as to gap (or gap is produced between above-mentioned tubular bolster and said reflection plate
Become big).On the other hand, it was found that following machine, i.e. exist even if making A-stage become between tubular bolster and reflecting plate
The state (or gap big state) in gap also occurs following movement：The said reflection plate because of the impact of the heat of backlight etc.
Generation bends, so as to gap of the above-mentioned tubular bolster with said reflection plate disappears (or gap diminishes).In other words, it is above-mentioned anti-
The flexure mode caused because of temperature for penetrating plate is different.And specify that, according to the presence or absence of above-mentioned gap, the size in above-mentioned gap,
Light quantity from said reflection plate has increased and decreased, thus the change of the brightness of above-mentioned display panels and above-mentioned optical sensor
The degree of association of measured value is simultaneously non-constant and have deviation.
Figure 20 is front view schematically known to observation during liquid crystal image display device 101.Figure 21 and Figure 22 are Figure 20
Line A-A sectional view, main portions sectional view when being liquid crystal image display device 101 viewed from above.Known liquid crystal figure
As display device 101 is configured with backlight 103 at the rear of display panels 102, it is configured with instead at the rear of backlight 103
Plate 104 is penetrated, panel sheet metal 105 is configured with the rear of reflecting plate 104, be configured with matrix sheet metal at the rear of panel sheet metal 105
106 (Figure 21, Figure 22).And, possess and determine the optical sensor 112 of the light from 104 back side of reflecting plate, be configured with optical sensor
112 substrate 111, and for prevent outer light enter optical sensor 112 tubular bolster 113 (Figure 21, Figure 22).And,
Substrate 111 is installed, in addition, the daylighting to clog panel sheet metal 105 in the way of the through hole 1061 for clogging matrix sheet metal 106
The mode in hole 1051 is provided with tubular bolster 113 (Figure 21, Figure 22).
According to the investigation of present inventor, following machine has been learnt:When the liquid crystal display being made up of symbol 102~105
During panel module heating, for example as shown in figure 22, the flexure mode of reflecting plate 104 and Figure 21 are conversely, the mediad of reflecting plate 104
Front (frontal) is mobile, and gap is changed into symbol S2 from symbol S1, increases hence into the light quantity of optical sensor 112.It is another
Aspect, has following machine:When above-mentioned LCD panel module heating, for example as shown in figure 21, the flexure side of reflecting plate 104
Conversely, rearward (back side direction) is mobile in the central authorities of reflecting plate 104, gap is changed into symbol S1 from symbol S2 for formula and Figure 22, so as to
Light quantity into optical sensor 112 is reduced.And specify that, according to the presence or absence of above-mentioned gap, the size in above-mentioned gap, come reflexive
The light quantity for penetrating plate 104 has increased and decreased, thus the change of the brightness of display panels 102 and the measured value of optical sensor 112
Degree of association is simultaneously non-constant and have deviation.
As noted above it is believed that with large screen, the progress being thinned of liquid crystal image display device, when reflecting plate bends
Deflection also becoming big, its degree of flexibility depends on temperature, external force etc. to be affected, it is difficult to predict, as a result, LCD
The degree of association of the change of the brightness of plate and the measured value of optical sensor is simultaneously non-constant and have deviation.
